Description of Path Item not shown

Demonstration API definition

{
  "info": {
    "title": "Sample Pet Store App",
    "description": "This is a sample server for a pet store.",
    "version": "1.0.1"
  },
  "openapi": "3.0.0",
  "paths": {
    "/foo": {
      "description": "This Should be Displayed!",
      "get": {
        "responses": {
          "204": {
            "description": "OK"
          }
        }
      }
    }
  }
}

Expected Behavior

When there is no description on the Operation Object, the description from the Path Item Object should be shown instead. (Otherwise I would have to repeat my description for ever operation)

This would comply with the Specification:

An optional, string description, intended to apply to all operations in this path.

Current Behavior

The description, (in the above example This Should be Displayed! should be shown in the place where normally the Operation description is shown.

Context

I want to avoid to reduntantly paste the same description string to every Operation there is for a path.

Use the supplied OpenAPI 3.0.0 definition in Swagger Editor online to reproduce the missing Path Item description, then trace the Swagger UI path and operation rendering entry point. Done means a Path Item description is displayed when an operation has no description, without requiring the text to be repeated for every operation.
